Nighttime basal dosing device

Abstract

A basal hub for attaching to an infusion base is disclosed. The hub includes a fluid reservoir and pressure actuating device. A septum portion of the reservoir is configured to be opened by a flow cannula that is in fluid communication with an infusion cannula of the infusion base, when the basal hub is attached to the infusion base. The pressure actuating device applies pressure to the fluid reservoir, such that when the septum portion of the fluid reservoir is pierced by the by the flow cannula, liquid stored in the fluid reservoir is released from the fluid reservoir into the infusion cannula of the infusion base via the flow cannula. The basal hub is configured to deliver a basal dose of insulin during periods of inactivity, such as during sleep time.

What is claimed is: 
     
       1. A method of administering liquid medication to a patient, comprising:
 during a first period of time, administering liquid medication to the patient only from a remote infusion pump through an extension set attached to an infusion base that is attached to the patient; and 
 during a second period of time, administering liquid medication to the patient only from a reservoir pressurized by a preloaded compression element and contained in a basal hub attached directly to the infusion base in a manner preventing the simultaneous attachment of an extension set to the infusion base. 
 
     
     
       2. The method as claimed in  claim 1 , wherein the extension set comprises a set hub and a tube set, the tube set being connected to the set hub and the pump to deliver liquid medication from the pump into an infusion cannula of the set hub. 
     
     
       3. The method as claimed in  claim 1 , wherein the basal hub delivers liquid medication from the reservoir into an infusion cannula of the infusion base. 
     
     
       4. The method as claimed in  claim 1 , wherein the first period of time is a waking period and the second period of time is a sleeping or resting period. 
     
     
       5. The method as claimed in  claim 1 , wherein the first period of time is a daytime period and the second period of time is a nighttime period. 
     
     
       6. The method as claimed in  claim 1 , wherein the basal hub is configured to deliver a basal dose of liquid medication during periods of inactivity. 
     
     
       7. The method as claimed in  claim 1 , wherein liquid medication comprises insulin. 
     
     
       8. The method as claimed in  claim 1 , wherein the preloaded compression element comprises a spring or a membrane. 
     
     
       9. A method of administering liquid medication to a patient, comprising:
 during a first period of time, administering liquid medication to the patient from a remote infusion pump through an extension set to an infusion base that is attached to the patient; 
 detaching the extension set from the infusion base; 
 during a second period of time, administering liquid medication to the patient from a reservoir in a basal hub attached to the infusion base; and 
 after the step of detaching the extension set from the infusion base and before the second period of time, implementing a command from an infusion pump controller to fill the reservoir of the basal hub with a quantity of liquid medication required for a basal dose, and recording the basal dose as a bolus dose by the infusion pump. 
 
     
     
       10. A method of administering liquid medication to a patient, comprising:
 during a first period of time, administering liquid medication to the patient from a remote infusion pump through an extension set to an infusion base that is attached to the patient; 
 detaching the extension set from the infusion base; 
 during a second period of time, administering liquid medication to the patient from a reservoir in a basal hub attached to the infusion base; 
 after the step of detaching the extension set from the infusion base and before the second period of time, implementing a command from an infusion pump controller to fill the reservoir of the basal hub with a quantity of liquid medication required for a basal dose; and 
 capturing a total dose delivered during a period of sleep or inactivity as part of a total daily dose.
